It was reviewed by the NOAA Office for Coastal Management at the macro level, which included checking for format and point characteristics for approximately 5% of the tiles. In addition, the entire data set was reviewed to establish that bare earth processing and proper classification of the points had been performed. It did not include accuracy or data processing (e.g. bare earth quality, flightline mismatch, feature removal) assessments. Based on the limited review, the data set on average appeared to be of fair quality. This determination is based on the issues listed under the reviews below. Again, no accuracy assessment was performed. The results may be viewed as a formatted document. This document is entitled "Lidar Fact Sheet: Jackson County, Texas," and may be viewed at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/92/supplemental/JacksonCounty_factsheet.pdf Tile Review There is a reoccurring formatting or possible data storage issue, which has been noted in the other Texas data. This issue is classification of the first of two returns (i.e., the highest return from a single pulse) as ground points; it is fundamentally incorrect. While it may not have any relation to the actual data accuracy, it renders all return information suspect. Additionally, water is not classified - nor was there any apparent attempt to do so. Bare Earth Point Density Review There is a distinct difference between the northeastern portion of the county and the main portion of the county in terms of ground point densities; the northeastern portion has a consistently higher density. There are also some lower density tiles in the central-northern portion of the county that indicate some tile-specific processing. The striping in water clearly indicates a lack of water classification. Additionally, at the time of the review, there were a few missing and corrupt tiles.

The data acquisition occurred in 6 missions between April 9, 2006, April 16, 2006, April 17, 2006, and May 11, 2006 through May 13, 2006. During the LIDAR campaign, the Sanborn field crew conducted a GPS field survey to establish final coordinates of the ground base stations for final processing of the base-remote GPS solutions. dateTime: DateTime: 2007-08-01T00:00:00 processStep: (LI_ProcessStep) description: Airborne GPS Processing: Airborne GPS data was differentially processed and integrated with the post processed IMU data to derive a smoothed best estimate of trajectory (SBET). The SBET was used to reduce the LiDAR slant range measurements to a raw reflective surface for each flight line. The overlap between flight lines was removed to provide a homogeneous coverage, and the coverage was classified to extract a bare earth digital elevation model (DEM). Airborne GPS is differentially processed using the GrafNAV V7.50 software by Waypoint Consulting of Calgary, Alberta, Canada. The PDOP and distance separation is as follows: IMU data is processed using the PosPac V4.2 software by Applanix Corporation of Richmond Hill, Ontario, Canada. The reflective surface is derived using the ALS Post Processor software by Leica Geosystems GIS & Mapping Division of Atlanta, Georgia. The classification and quality control (QC) of LiDAR data is carried out using TerraScan software by Terrasolid Limited of Helsinki, Finland. dateTime: DateTime: 2007-08-01T00:00:00 processStep: (LI_ProcessStep) description: IMU data Processing: IMU data provides information concerning roll, pitch, and yaw of collection platform during collection event. IMU information allows the pulse vector to be properly placed in 3D space allowing the distance from the aircraft reference point to be properly positioned on the elevation model surface. IMU data is processed using the PosPac V4.2 software by Applanix Corporation of Richmond Hill, Ontario, Canada. dateTime: DateTime: 2007-08-01T00:00:00 processStep: (LI_ProcessStep) description: Reflective Surface Generation: The reflective surface is derived using the ALS Post Processor software by Leica Geosystems GIS & Mapping Division of Atlanta, Georgia. dateTime: DateTime: 2007-08-01T00:00:00 processStep: (LI_ProcessStep) description: LIDAR Point Classification The classification and quality control (QC) of LiDAR data is carried out using TerraScan software by Terrasolid Limited of Helsinki, Finland. dateTime: DateTime: 2007-08-01T00:00:00 processStep: (LI_ProcessStep) description: Output LAS Files The product output of LiDAR data is carried out using TerraScan software by Terrasolid Limited of Helsinki, Finland.

The files contained Lidar elevation and intensity measurements. The data was in UTM projection, and NAVD88 Geoid 03 vertical datum. OCM performed the following processing to the data to make it available within the Digital Coast: 1. The data were converted from UTM coordinates to geographic coordinates. 2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03. 3. The LAS data were sorted by latitude and the headers were updated. NOAA OCM also performed a macro level review of this data set. This review involved checking for format and point characteristics in about 5% of the tiles. In addition, the entire data set was reviewed to establish that bare-earth processing and proper classification of the points had been performed. This review did not include accuracy or data-processing (e.g., bare-earth quality, flightline mismatch, feature removal) assessments.
